The Sera marin COMPONENT 1 – 7 collection is designed for discerning marine aquarium enthusiasts, providing corals and other delicate aquatic life with seven essential, complementary ingredients. This formulation includes the vital trace element iodine. Seramarin COMPONENT 7 - iodine features the crucial trace element iodine. Iodine tends to be unstable in aquarium environments, quickly converting to iodide, which is less effective for many aquatic animals and plants. By incorporating Sera marin COMPONENT 7 - iodine daily, we ensure a stable iodine level, preventing concentration fluctuations and deficiencies. This product comes in a dropper bottle for easy and precise dosing. Dosage: It is recommended to add one drop of Sera marin COMPONENT 7 - iodine for every 100 liters of water, following the addition of Sera marin COMPONENT 5-strontium.

For easy tracking of the density of marine water The salinity (the amount of salt) can be inferred from the density readings. As the salinity level in an aquarium's marine water needs to remain stable, it's important to test the water periodically. To conduct the test, pour the water into a tall glass, and then read the scale on the submerged hydrometer based on how deep it is immersed.

Marine salt for R/O and tap water Thanks to its exceptional uniformity and consistent grain size, sera marin salt dissolves rapidly and leaves no residues, creating crystal clear marine water. It ensures natural GH and KH levels while supplying ample calcium and magnesium in biologically appropriate quantities. The pH level will consistently and accurately stay within the desired range, thanks to the natural buffering system found in sera marin salt. A unique process allows sera marin salt to maintain trace elements in a form that keeps them continuously available in solution for an extended period. Sera marin salt is free from any ingredients that would artificially enhance protein skimmer performance. It does not contain nitrates, silicates, or phosphates. Sera (sea salt devoid of nitrates, phosphates, and silicates) provides calcium along with all the essential trace elements required for the successful cultivation of ornamental algae and lower resins in seawater. It features a mix of specialized compounds that assist in the removal of harmful substances like heavy metals and copper. The salt dissolves quickly and leaves no residue. With its natural buffering system, it guarantees a consistently optimal pH value. Instructions for use: Dissolve Sera marin salt (approximately 33 g per liter of water) to achieve a water density between 1.022 and 1.024 g/ml in a container using treated water (osmosis) or chlorine-free tap water. Aerate for 24 hours or mix thoroughly with a submersible pump to ensure proper oxygen and carbon dioxide levels. Warning: Do not dissolve sea salt directly in an active aquarium! It is advised to change 5-10% of the aquarium water monthly, and additionally treat the water with sera aquatan and sera bio reef clear for improved water quality. When establishing a new aquarium, treat the water with Sera aquatan and Sera bio reef clear, and allow the aquarium with all connected equipment (pumps, heaters, filter, etc.) to operate for a minimum of 14 days to achieve biological stability before adding fish.  

Effective Silicate Elimination Silicates promote the proliferation of diatoms in both fresh and saltwater aquariums. Sera marin silicate clear effectively and permanently eliminates silicates. Sera marin silicate clear comes in a convenient filter media bag. Prior to use, rinse it briefly under running water, then simply insert it into a filter or place it in an area with good water circulation. Its effectiveness lasts for up to three months, depending on the level of silicates in the water. 60 g is suitable for a 20-50 liter aquarium 500 g is sufficient for a 200-400 liter aquarium Tip: The sera SiO 3 test can be used to accurately monitor the silicate levels.
